SPECIFICATION forming part of Letters Patent No. 394,807, dated December 18, 1888.

Application filed November 5, 1888. Serial No. 290,050. (No model.)

To all whom it may 007000772 Be it known that I, ALLAN II. ]-l.-\CON,-of \Vebster Groves, Missouri, have made a new and useful Improvement in Electrical Appliances, of which the following is a full, clear, and exact description.

The improvement is adaptable to a variety of tools having handles and designed for manual use.

It consists, mainly, in incorporating in a tool-handle an electric battery having conductors leading therefrom and so disposed about the handle and provided with such electrodes as to enable an electric current to be transmitted through the hand while manipu-' lating the tool.

The improvement is illustrated in connection with a pen or pencil holder, to which instrument it is especially suited.

In the annexed drawings, making part of this specification, Figure 1 is a view in perspective exemplifying the use of the improved holder; Fig. 2, a side elevation of the holder; 3, a longitudinal section of the holder; Fig. 4, a cross-section on the line at 4 of Fig. 2, and Fig. 5 a cross-section on the line 5 5 of Fig. 2. The last two views are upon an enlarged scale.

The same letters of reference applied to the several drawin denote the same parts.

The pen-holder A is of any of the usual constructions, saving as it may be modified or supplemented by the improvement in question. The case, handle, or holder a, as it may indifferently be called, is adapted at one end to receive and hold a pen, a, pencil, or other article to be held, and at the other end it may be finished in any suitable manner. In the present instance the holder is provided with a cap, (1 or other removable part suitable for closing the chamber a, formed within the holder for the reception of the battery l3, used for generi'tting the electric current.

I desire not to be restricted to any special battery or means for producing the electric current; but a desirable battery is shown. It is substantially such an one asi s employed in electric belts, being composed of cells I) I), suitably united by means of the connection I), and having suitable conductors, b I)", leading, respectively, from the ends of the bat tery. The conductors in turn lead to electrodes 0 (7,

which areot suitable material for conducting the electric current, and are so located upon or in the holder as to enable the hand D, broken lines, Fig. 1, of the person using the holder to readily come in contact with them. To this end the electrodes and the conductors may be variously disposed about'the holder; but, to enable the current to be transmitted through the thumb (Z and forefinger (Z of the hand, the electrodes are arranged upon oppo site sides of the holder, substantially as shown, and the conductors b b lead to them, as follows: The conductor b leads from the innermost cell, b, outward through the shell of the holder to the electrode 0, and the conductor I) leads from the outermost cell, c, outward through the holder-shell to its outer surface, and thence along the holder and to the electrode C. The electric current is transmitted whenever the hand is in contact with either the two electrodes or the conductors, or with one of the electrodes and the conductor leading to the other of the electrodes. The electrodes can be variously shaped and variously arranged, as stated, and when with them arranged as shown the conductors may lead in various ways to them. I consider, however, a desirable arrangcm cut is exhibited. The electrodes are countersunk in the surface of the holder, as well as that part of the conductor Z) which appears upon the outer side of the holder, as thereby no undesirable projection is formed upon the holder.

\Vhen it is desired to dispense with the electric current, theholder can be turned around, so that the hand in grasping it shall not form a contact with the electrodes, and to this end there are spaces (1" a" upon the holder between the electrodes, and the pen or pencil or other article may be so connected with the holder that in inserting it in the holder it can be turned around therein to conform to the position of the hand upon the holder.

In other forms of tools the electrodes are located to suit the position of the hand when applied to the tool.

\Vhen the battery is of the kind shown, itis adapted to be treated in the usual manner for renewing its strength. By employing a tight partition, as at a, Fig. 3, or otherwise making the chamber a practically tight, the acid liquid used in renewing the battery can be apelectrodes or elsewhere, substantially as described.

3. The eelnbii'latien of the holder, chainbe'red as described, the pen, the cap, the battery, the conductors, and the electrodes, substantially as described.

\Vitness my hand this 231st day of ()etelwr, 20

less.
